How to Sync Shopify to Mailchimp to Grow Your List FAST

Are you looking for ways to integrate your Shopify store with your Mailchimp account?

Mailchimp is one of the most popular email service providers (ESPs) that lets you send automated campaigns at an affordable price.

However, they recently discontinued their Shopify integration so you’ll need to find other ways to connect your accounts.

In this guide, you’ll learn the easiest and best way to connect your Shopify store to your Mailchimp account. This method is not only fast but it also lets you grow your email list, improves engagement, and boosts sales.

Before we dive in though, let’s see why we chose our method and how it compares to other options out there.

The BEST Way to Sync Shopify to Mailchimp

There are a few apps available in the Shopify app store that let you connect your store to a Mailchimp account.

For instance, there’s ShopSync that lets you integrate the 2 platforms, and it will even import all your store info into your Mailchimp accounts (such as customers, orders, and products).

But there’s a huge downside to this kind of connection.

If an existing email subscriber buys something from your store, Shopify adds them as a ‘transactional only’ customer.

This means going forward, these subscribers will receive only transactional emails such as order confirmations and delivery updates.

Plus, if a returning customer does not opt into marketing emails each time they purchase something, Shopify will automatically tag them as ‘transactional’ and unsubscribe them from marketing emails.

What this means for you is a pile of administrative work where you’ll need to manually re-add contacts to your marketing email list.

Aside from that, these apps don’t have features like sign-up forms and lead generation campaigns to get more email subscribers and target customers to increase sales.

Our OptinMonster app overcomes these challenges and is packed with powerful lead generation features.

OptinMonster is hands down the #1 lead generation tool for Shopify.

It lets you connect to Mailchimp in just a few clicks. The seamless integration happens behind the scenes without any technical work on your end.

Once you’ve connected OptinMonster to Mailchimp, it will automatically send all leads collected on your Shopify site to your Mailchimp contact list.

You can then trigger automated emails to new subscribers to welcome them to your brand.

Also, OptinMonster lets you tag your subscribers so that they’re segmented right from the start.

This means you can organize the leads you collect based on what they signed up for, like your newsletter, webinar, or other marketing campaigns.

That means you can be sure the subscriber gets relevant emails from you.

OptinMonster also comes with a really cool lead verification addon called TruLead®.

With TruLead®, OptinMonster will automatically:

  • block spam entries
  • block bad bots
  • auto-fix common email address spelling errors
  • block free or temp email addresses

You can be sure only genuine email addresses are sent to your Mailchimp contact list.

Now here’s where OptinMonster’s features get really interesting: to maximize leads from your Shopify store, OptinMonster lets you create all kinds of campaigns like popups, floating bars, slide-ins, fullscreen mats, inline forms, gamified wheels, and more.

You can choose from 50+ beautiful premade templates to match your marketing goals like holiday sales, lead magnet offers, and limited-period discounts.

OptinMonster comes with a beginner-friendly drag and drop builder that lets you customize your designs in a matter of minutes.

But the best part about OptinMonster is its powerful targeting features to show your campaigns at the right time, in the right places, and to just the right people.

There are targeting rules that are designed just for Shopify stores, too. This means you can target customers based on:

  • what actions they take on your site
  • where they are located
  • what products they show interest in
  • which page they’re viewing
  • whether they are a new or returning visitor

…and much more.

So, for example, using OptinMonster’s Exit-Intent® technology, you can detect when visitors are about to leave your site and show them a campaign to try to convert them before they leave.

This will open up a page where you can select a campaign type and template.

OptinMonster lets you create lightbox popups, floating bars, inline forms, slide-ins, gamified wheels, and more.

When you select a template, OptinMonster will ask you to name your campaign, so you can easily find it among all the campaigns you create.

Click on the ‘Start Building‘ button to enter the OptinMonster campaign builder where you can customize your design.

Step 2: Customizing the OptinMonster Campaign

OptinMonster’s templates are ready to use out of the box. However, you may want to change the text, colors, and add your own image/logo to match your brand and marketing goals.

OptinMonster makes it incredibly easy to customize the template. The campaign is made up of blocks, so you can select any block to edit it.

For instance, if you want to change the text, simply select it and type in your own. And when you select all the text, you’ll see a text editor with options to change the font family, font size, color, alignment, and much more.

Then simply drag and drop the block you want into the campaign.

Once you use OptinMonster, you’ll learn that it gives you far better control over your lead generation forms compared to Mailchimp’s form builder.

Next, we’ll show you how to set up display rules to target customers with relevant campaigns. This will help maximize the number of email subscribers you get.

Step 3: Setting Up Display Rules

OptinMonster’s advanced targeting rules let you display your campaign to the right customers to optimize conversion rates. You can set up these targeting rules under the ‘Display Rules‘ tab in the campaign builder.

When you click the ‘Connect to Mailchimp’ button, you’ll see a new field appear to select an Email Providers List.


OptinMonster fetches the audience lists you’ve created in Mailchimp and lets you select them here. After selecting a list, you’ll see more options to select a Mailchimp tag to further organize your subscribers.

For example, you can create a tag in Mailchimp called ‘Newsletter‘ and then select that same tag here. All the leads collected through this campaign will be added to the Newsletter list.

Then when you send out your weekly newsletter, it’ll go only to those who have signed up for your newsletter. This helps reduce unsubscribe rates, spam flags, and keeps your list clean.
